IMSA has confirmed the 2025 WeatherTech SportsCar Championship schedule, some five months ahead of its traditional release date. The calendar is unchanged from 2024

This morning at Sebring International Raceway – site of Saturday’s 72nd Mobil 1 Twelve Hours of Sebring Presented by Cadillac – IMSA President John Doonan revealed the slate of races that will make up the 2025 schedules for the WeatherTech Championship and the IMSA Michelin Pilot Challenge. The announcement was made in a gathering of IMSA stakeholders at the track.

Showcasing the stability and consistency that IMSA fans, competitors and stakeholders have come to expect, the 2025 schedules will not differ substantially from this year’s calendar. The WeatherTech Championship once again will include an 11-race season, including five endurance events that will comprise the IMSA Michelin Endurance Cup.

The Michelin Pilot Challenge again will feature a 10-race schedule, including one standalone event in which the series is the featured race.

“On behalf of my teammates at IMSA, I am proud to be able to announce our schedule for 2025 at such an early date,” said Doonan. “This was made possible through a great spirit of collaboration with our promoter partners, and we are grateful to them for enabling us to make our 2025 plans known today. Putting next year’s schedule into everybody’s hands so soon allows fans, competitors and partners to get well ahead in planning for an amazing 2025 season, even with so much of our 2024 season still to come.”

The 2025 season will open in Daytona Beach, Florida with the 63rd Rolex 24 At Daytona on the weekend of Jan. 23-26 as confirmed in an announcement last week from Daytona International Speedway.

The Daytona and Sebring events both will include all four WeatherTech Championship classes: Grand Touring Prototype (GTP), Le Mans Prototype 2 (LMP2), Grand Touring Daytona Pro (GTD PRO) and Grand Touring Daytona (GTD).

After the pair of Florida endurance races, the WeatherTech Championship will make its traditional western trek to the Acura Grand Prix of Long Beach, which will feature the GTP and GTD classes in a 100-minute battle on the famed streets of the Southern California city. That event weekend is scheduled for April 11-12.

The event will bring together all four WeatherTech Championship classes for the first time since Sebring.

Three WeatherTech Championship classes – LMP2, GTD PRO and GTD – will be showcased at Canadian Tire Motorsport Park in Bowmanville, Ontario on the weekend of July 11-13 in the series’ lone visit north of the border. All four classes return to action on the weekend of July 31-Aug. 3 for the annual WeatherTech Championship visit to Road America in Elkhart Lake, Wisconsin.
